Concealed carry of a handgun in the united states is a right granted to you from the 2nd amendment not all states allow this though and some are very restictive on this issue.
Supporters of concealed carry argue that criminals are less likely to attack if they believe the potential victim could be armed. They also cite the provisions of the Second Amendment and contend that most adults who legally carry a concealed handgun are law-abiding citizens.Meanwhile, critics argue that increased gun ownership leads to more gun crime and that concealed handguns boost the chances of rguments becoming lethal, and increase the number of unintended gun injuries. However, recent research conducted by David Burnett and Clayton Cramer, who track incidents of defensive gun use at TheArmedCitizen.com, found that concealed guns may in fact save lives.
This issue is a big debate that has been going on for along time and there is many diffrent groups that are pro and con for the issue.
There are many support groups that consider a handgun non leathal and the best defense against an attacker or criminal
Legally, a line is sometimes drawn between lethal and non-lethal force, and sometimes not.
Statistics show that an attacker is 75% less like to attck some they may think is armed
Personal carry in my view is a right and a need you should be able to protect your self from an armed criminal even if the danger would make you presnt a firearm and potentonally take a life.
And legally no just anyone can carry a concealed handgun background checks are required and you must register you handgun and if you are a convicted felon you are not allowed to purchase posses a firearm.
Individuals qualify for concealed weapon licenses in these states upon reaching 18 years of age. HOWEVER, any licensee of these reciprocity states who is not 21 years of age or older IS PROHIBITED from carrying a concealed weapon or firearm in Florida.
